Keyvan Chemirani
No full textPercussionniste de tradition persane, Keyvan Chemirani n’a pourtant jamais expérimenté cet héritage paternel dans son écho-système d’origine. Il retrace son parcours atypique de musicien et de compositeur français, soulevant les questions de légitimité qui ont freiné ses premiers pas. Il rend aussi hommage au formidable esprit d’ouverture que son père et maître, Djamchid Chemirani, a su lui insuffler. Son récit dessine une autre forme de développement artistique, prenant sa source dans une tradition multiséculaire, mais construisant une carrière en dehors des normes et menant à des processus de création inusités

Preparation of Highly Active 40?wt.% Pt on Multiwalled Carbon Nanotube by Improved Impregnation Method for Fuel Cell Applications
No full text40 wt.% Pt catalyst supported on multiwalled carbon nanotube (MWCNT) was successfully synthesized by using improved aqueous impregnation method. Catalysts were characterized by HR-TEM, XRD, and X-Ray photoelectron spectroscopy. Electrocatalytic performance of the catalyst materials was investigated by electrochemical half cell test measurements. According to the results of electrochemical measurements, synthesized Pt/MWCNT catalyst presented high electrochemical activity which is mostly due to high utilization of catalyst particles and good physical properties of MWCNT supporting material. It was revealed that, improved aqueous impregnation method has a satisfactory efficiency for production of Pt/MWCNT catalyst. © 2012 WILEY-VCH Verlag GmbH & Co. KGaA,Weinheim.
Synthesis and electrocatalytic performance of high loading active PtRu multiwalled carbon nanotube catalyst for methanol oxidation
No full textMultiwalled carbon nanotube (MWCNT) supported PtRu catalyst was prepared by improved aqueous impregnation method. The catalyst nanoparticles were characterized by using high resolution transmission electron microscopy (HR-TEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) measurements. According to the results of physicochemical characterization, PtRu alloy nanoparticles with low content of surface oxidation states were successfully synthesized on the outer surface of MWCNT supporting materials. Electrocatalytic activity of catalyst materials was investigated by using electrochemical half cell and CO stripping analyses. Results of electrochemical measurements indicate that the prepared PtRu/MWCNT catalyst shows an enhanced electrochemical activity toward methanol oxidation and a high electrocatalytic activity for CO oxidation. It is believed that superior performance of the PtRu/MWCNT catalyst is mostly attributed to the high degree of alloy formation and low contents of oxidized species of Pt and Ru. © 2012 Elsevier Ltd.

An Introduction to Teledermatology
No full textTeledermatologyTeledermatology (TD) encompasses the interpretation of a patient’s clinical history in conjunction with electronically transmitted images, in order to make a diagnosis and provide appropriate treatment recommendations. Three main platforms are currently being utilized: synchronous (real-time video consultation), asynchronousStore-and-forward (store-and-forward [SAF]), and hybrid. The main advantage provided by the use of telemedicineTelemedicinein dermatologyDermatology is easier access to specialized medical care, especially for underservedUnderserved patients and those limited by geographical barriers. TD can also be a useful tool for triaging patients, as well as a valuable asset in training residents and physicians. Furthermore, teledermatology consultations can be used in both the outpatient and inpatient setting, with many studies supporting its reliability and accuracy when compared to in-person consultations. Some barriers for its use to consider include the dependence on image/video quality, limited interaction between patients and physicians, medicolegal implications, and ethical concerns surrounding the shift of a patient-centered approach to a technologyTechnology-centered one

International Perspective of Mohs Micrographic Surgery: East Asia
No full textOverall skin cancerSkin cancer rates are much lower in East Asian populations than in Caucasian populations. Pigmented basal cell carcinomaBasal cell carcinoma (BCC) is the most common type, and surgical excisionSurgical excision with wide margins is the standard treatmentTreatment for BCC in most East Asian countries. Due to differences among countries in insurance systems and surgical approaches, Mohs micrographic surgeryMohs micrographic surgery (MMS) is an uncommon procedure in most Asian countries. Surgical excisionSurgical excision is widely used in the major parts of East Asia because of its effectiveness and simplicity. MMS has been reported to be a successful treatmentTreatment by particular institutions in Korea and Taiwan. However, MMS is not routinely available in most dermatologic units in East Asia. Intraoperative histological evaluation to control surgical margins is widely used instead of MMS for high-risk skin cancerSkin cancer. Complete histological margin control using a double-bladed scalpel may be easily applied to standard intraoperative frozen sectionFrozen sections evaluation in many institutions where MMS is difficult to perform. It is far less time-consuming and can be easily used by surgeons with existing systems, even in East Asian countries
A wolf in sheep's clothing: Exposing the structural violence of private electric automobility
No full textThe world is running out of time to avoid cataclysmic climate impacts. Therefore, determining which decarbonisation strategies are more effective and inclusive in reducing anthropogenic dependency on fossil fuels is vital for governments' decisions on investment. This research argues that the electrification of private automobility is neither effective nor equitable. Considering the current electricity mix of the grid, this electrification merely shifts the CO2 emissions and other pollutants from urban to rural areas. The strategy of private automobility electrification does not look beyond the problem of tailpipe emissions and hence cannot eliminate the deficiencies of the car-dependent system that require system-wide solutions, such as traffic congestion and road accidents. Prioritising this strategy not only maintains existing inequities but also increases social injustice and delays the implementation of more effective interventions. We argue that using private EVs structurally violates the biosphere and human communities in three ways: (1) production of inequities, (2) pollution and waste, and (3) the space of the exception (the ‘Electric Vehicle Bubble’). Finally, we conclude that eradicating private automobility is necessary to realise climate and transport justice. Focusing on inclusive strategies, such as supporting public transportation, shared mobility, and active travel modes, instead of offering incentives for EVs, are the means of progressive redistribution of wealth and can satisfactorily meet people's basic needs and governmental climate targets.<br/
